(NewsNation) — U.S. President Joe Biden and other world leaders were reflecting on the life of Queen Elizabeth II following her death Thursday at the age of 96.

King Charles III

“The death of my beloved Mother, Her Majesty The Queen, is a moment of the greatest sadness for me and all members of my family.

“We mourn profoundly the passing of a cherished Sovereign and a much-loved Mother. I know her loss will be deeply felt throughout the country, the Realms and the Commonwealth, and by countless people around the world.

“During this period of mourning and change, my family and I will be comforted and sustained by our knowledge of the respect and deep affection in which The Queen was so widely held.”

U.S. President Joe Biden

“Queen Elizabeth II was a stateswoman of unmatched dignity and constancy who deepened the bedrock Alliance between the United Kingdom and the United States. She helped make our relationship special.

“We first met the Queen in 1982, traveling to the UK as part of a Senate delegation. And we were honored that she extended her hospitality to us in June 2021 during our first overseas trip as President and First Lady, where she charmed us with her wit, moved us with her kindness, and generously shared with us her wisdom. All told, she met 14 American presidents. She helped Americans commemorate both the anniversary of the founding of Jamestown and the bicentennial of our independence. And she stood in solidarity with the United States during our darkest days after 9/11, when she poignantly reminded us that ‘Grief is the price we pay for love,'” the statement read in part.

Biden also issued a proclamation to fly the U.S. flag at half-staff as a “mark of respect for the memory” of the queen until sunset on the day of her interment.

The president told the Daily Mail he would “probably” attend the queen’s funeral.

UK Prime Minister Liz Truss

“Queen Elizabeth II was the rock on which modern Britain was built. Our country has grown and flourished under her reign,” the new prime minister of the United Kingdom, Liz Truss, wrote in a statement on the death of the queen. It is her second day in office after officially taking over the position Wednesday.

“In the difficult days ahead, we will come together with our friends across the United Kingdom, the Commonwealth and the world to celebrate her extraordinary lifetime of service. It is a day of great loss, but Queen Elizabeth II leaves a great legacy. God save the King.”

Former UK Prime Minister Boris Johnson

“This is our country’s saddest day. In the hearts of every one of us there is an ache at the passing of our Queen, a deep and personal sense of loss — far more intense, perhaps, than we expected,” the former prime minister wrote in part in a statement.

“As is so natural with human beings, it is only when we face the reality of our loss that we truly understand what has gone. It is only really now that we grasp how much she meant for us, how much she did for us, how much she loved us,” he continued. “As we think of the voice she leaves, we understand the vital role she played, selflessly and calmly embodying the continuity and unity of our country.”

Former U.S. President Donald Trump

“Melania and I are deeply saddened to learn of the loss of Her Majesty Queen Elizabeth II. Together with our family and fellow Americans, we send our sincere condolences to the Royal Family and the people of the United Kingdom during this time of great sorrow and grief. Queen Elizabeth’s historic and remarkable reign left a tremendous legacy of peace and prosperity for Great Britain,” the statement read in part.

former u.s. President Barack Obama

“Michelle and I were lucky enough to come to know Her Majesty, and she meant a great deal to us. Back when we were just beginning to navigate life as President and First Lady, she welcomed us to the world stage with open and extraordinary generosity.

“Like so many, Michelle and I are grateful to have witnessed Her Majesty’s dedicated leadership, and we are awed by her legacy of tireless, dignified public service. Our thoughts are with her family and the people of the United Kingdom at this difficult time,” the statement read in part.

Former U.S. President Bill Clinton

“We will always be grateful for the kindness she showed us through the years, particularly during our visits to Buckingham Palace in 1995 and 2000, and for all she did to deepen the Special Relationship.

“Our thoughts and prayers are with the Royal Family and all the people Her Majesty inspired throughout her lifetime of service,” the statement read in part.

French President Emmanuel Macron

“Her Majesty Queen Elizabeth II embodied the British nation’s continuity and unity for over 70 years. I remember her as a friend of France, a kind-hearted queen who has left a lasting impression on her country and her century,” the statement read in part.

Canadian Prime Minister Justin Trudeau 

“It was with the heaviest of hearts that we learned of the passing of Canada’s longest-reigning Sovereign, Her Majesty Queen Elizabeth II. She was a constant presence in our lives — and her service to Canadians will forever remain an important part of our country’s history. As we look back at her life and her reign that spanned so many decades, Canadians will always remember and cherish Her Majesty’s wisdom, compassion, and warmth. Our thoughts are with the members of the Royal Family during this most difficult time,” the statement read.

Irish Prime Minister Micheál Martin

“On behalf of the Government of Ireland, I would like to convey my deepest sympathy to His Majesty King Charles, the Royal Family, the UK Government and the British people on the loss of their beloved monarch, Her Majesty Queen Elizabeth. 

“The Queen’s reign was one of historic duration, immense consequence and a focus of respect and admiration around the world. Her dedication to duty and public service were self-evident and her wisdom and experience truly unique,” the statement read in part.
